Answer is Right!
Answer is Wrong!
The correct answer is: B. Crest and Crest.
A wave is a disturbance that travels through a medium from one point to another. The distance between two consecutive crests or troughs is called the wavelength.
Crest: The highest point of a wave.
Trough: The lowest point of a wave.
The wavelength of a wave is a measure of its size. It is determined by the speed of the wave and the frequency of the wave. The speed of a wave is the distance it travels in a given amount of time. The frequency of a wave is the number of waves that pass a given point in a given amount of time.
The wavelength of a wave is important because it determines the properties of the wave, such as its speed, frequency, and energy.
